- Application filed November 17. 1908. Serial No. 343.788;

To all whom it may concern:

Be it known that I, FRANK-L. BADER, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Im rovements in Metallic Weather-Strippi g; nd I do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to provide simple and effective metallic Weatherstrip.- ping especially designed for swinging cases ments or the like, in combination with a me ta llic stop-rail, said invention consisting in certain peculiarities of construction and combination of parts, as hereinafter fully set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a vertical section of a portion of the sill of a window-frame and swinging window-sash having secured thereto weather-stripping embodying the features of my inventlon; Fig. 2, a similar view showing the window-sash swung partly open and the position assumed by the metallic strip at this time, and Fig. 3 a face View of a portion of the strip and adjacent parts.

Referring by letters to the drawings, A indicates the sill of a window, and B the lower sash-rail thereof, which is arranged upon hinges (not shown) to be swung open vertically. Extending across the entire width of the window-sill and secured theretois an angle-iron stop-rail C, that is preferably gal vanized to prevent rusting, a vertical flange a oi the rail being rounded upon its edge and the basebthcroof formed with (lrain-open ings 0 adjacent to the flange.

The window, as previously stated, is arranged to open inwardly, and when closed a metallic spring-strip D, which is secured to the lower outer face of the sash, engages and rests upon the rounded edge of flange a, of the stop-rail, a depending lip d of the strip being arranged to press tightly against the inner face of the flange a and the outer face of the sash.

The spring-strip l) at its up turned at e to form a watcr-s1ed, which in turn is fitted into a groove f of the sash, and below the water-shed said strip is flattened' against and er edge is insecured to the sash by means of screws g, the aforesaid strip being flared outward from the sash at this point and having its free end bent into an ogee curve which terminates in the depending lip portion (1, previously described. The circular portion of the ogee curve h adjacent the de ending lip fgrms a pocket in which the rounded edge 0 t e flange crests, while the circular portion 11 of said curve, which emerges into the flared portion of the strips, serves as a catch which strikes said flange a as the window is closed, causing the strip to rise up as it contacts with the flange, thereby exerting a pressure or tension upon the latter in a downward direction at the same time the lip is exerting a similar pressure at a right angle thereto, thus insuring a tight joint in two directions. y

By thevabove description it will be seen that the metallic st 'p comprising the sash member owing to its eculiar formation will readily engage the ange ofthe stop-rail comprising the casing member and the two corn ining to-form a perfect seal, shrinkage or swelling of the wood being compensated for by the spring in the metal. Theiogee curve in thestrip proof, torathe reason that when any water drains from the window over the strip the capillary attraction thereof would be broken upon its return over the lower curve It to the flange a; but should it be possible for moisture to pass between the joint formed by said flange and strip it would be trapped and drained from the stop-rail by the openings 0, which are provided for this contingency.

' I claim A metallic weather -fstrip com rising a swinging door or sash member liaving a flared extension terminating in an ogee curve, a lip depending from the ogee curve, in combination with a stop-rail provided with a flange for engagement with the lip and ogeecurved portion of the strip.

In testimony that I claim' the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State 'of Wisconsin, in the presence of two witnesses.
